किस कथन में गुणोत्तर श्रेढ़ी \(18,6,2,\frac{2}{3},\ldots\) का सही वर्णन है?
Which statement correctly describes the geometric progression \(18,6,2,\frac{2}{3},\ldots\)?
Explanation opens after your attempt
Correct Answer
B. \(r=\frac{1}{3}\) और श्रेढ़ी घटती है\(r=\frac{1}{3}\) and the progression decreases
Concept
Each term is \(\frac{1}{3}\) of the previous term, so the progression decreases. Check both the value and direction of the ratio.
Why this answer is correct
The correct answer is B. \(r=\frac{1}{3}\) और श्रेढ़ी घटती है / \(r=\frac{1}{3}\) and the progression decreases. Each term is \(\frac{1}{3}\) of the previous term, so the progression decreases. Check both the value and direction of the ratio.
Exam Tip
हर पद पिछले पद का \(\frac{1}{3}\) है, इसलिए श्रेढ़ी घटती है। अनुपात की दिशा और मान दोनों देखें।
